REPORT OF STATE BOARD OF FISH COMMISSIONERS. 61 



to Kamloops Lake and secured the two type specimens, which were care- 

 fully placed in alcohol and sent to me. The following statement of their 

 habitat was furnished me by Mr. Bassett: 



These specimens were taken at the outlet of Kamloops Lake into the South Thompson; 

 the jsorth Thompson River flows into the upper end of the same lake. These waters 

 connect with the Shuswap Lakes, and this fish we find in all the tributaries of the last 

 named lakes, also in Okanagan Lake, the waters of which flow towards the Columbia 

 (the other lakes being tributary to the Fraser River). Reliable information gives the 

 weight of the largest spcimen ever caught in Okanagan Lake as 17K pounds. The 

 Shuswap Indian name for this salmon is SHt-tse. They have been taken flfty miles 

 below the Kamloops Lake in the Thompson River, biit not in large numbers. 



Mr. Bassett has since informed me that the species is found also in 

 Kootenay Lake, and that it is locally known as Silver trout. 



This seems to be a species of trout distinct from those hitherto authen- 

 tically recorded from the waters of the Pacific Coast. There is not much 

 doubt, from the account of Mr. Bassett, as well as from the appearance 

 of the fish, that it is a "land-locked" species. Its nearest relationships 

 seem to be with the Steel-head trout, or Salmon trout {Salm.o gairdneri), 

 from which it.differs somewhat in coloration, and especially in the longer 

 pectoral fin and in the form of the preopercle. It is, however, not un- 

 likely that it is descended from Salmo gairdneri. This species is really 

 intermediate between the ordinary trout and the Pacific salmon, com- 

 posing the genus Oncorhynchus, and its characters indicate the necessity 

 of replacing all in the genus Salmo. 



I have given the species the name of the lake from which it was first 

 taken. One of the two type specimens has been sent to the United States 

 National Museum, and the other is in the museum of the Leland Stanford, 

 Junior, University. With these two specimens was a small fish about 

 5 inches long, of the kind on which these salmon were  feeding. This 

 little fish was without spots, and has some 18 rays in the anal fin. Ap- 

 parently it is the young of the Quinnat salmon; certainly it is not the 

 young of the species in question.
